Christine Royles of South Portland, who suffered kidney failure because of an autoimmune disease, went on the national waiting list to find a donor, but decided to take matters into her own hands. The 24-year-old waitress and mother of a 2-year-old boy painted an appeal on her car's rear window, along with a phone number, according to the Portland Press Herald (http://bit.ly/1BVLJ6I ). People in need of an organ transplant are increasingly expanding their search beyond the national donor list and family members and friends, said Sean Roach, spokesman for the National Kidney Foundation.
